I have a Q series:
Mine was still in the mummy wrap from the arsenal refurb. Interesting thing about French refurbs - when the re-parkerize their rifles, they do not plug the barrels; they just parkerize the bores at the same time!
I also have a Santa Fe sporterized Mlle 36. I am thinking about converting it to 308. It shouldn't be hard. The barrel threads are the same as an SKS. I would need to weld up the extractor a little bit and devise some sort of safety.
